This concentration of sugar in the blood fluctuates from 100 milligrams of sugar in 100 cubic centimeters of blood to 180 milligrams. When it exceeds 180 milligrams the kidneys release the excess into urine and it is lost from the body. The level at which the kidneys release the sugar is called the "threshold". The constant handling of large excess of sugar by these kidney cells is held by some writers to be one cause of kidney cell damage.

Sugar and the pancreas

Sugar is rapidly absorbed from the digestive tract into the blood and if large amounts are eaten at a time so that it enters the blood faster than the body can use or store it, the result will be a "high tide" of sugar in the blood. It is said that in this case the pancreas secretes a large amount of insulin than it normally does. If this is continued over a considerable period until the cells of the pancreas are depleted, diabetes could result.

I have been often asked why do I not consume sugar and food that contains sugar. There are many different sorces of sugar that I will mention in my later postings. Many are wondering how it is possible to survive without cakes, candies or cookies that you can purchase in the shop. Nowdays its not so easy to get food without "bad sugar". I have to be very selective in shop, reading carefully labels. BUT I have A LOT of other subsidies for "sweet" things, like fruits, honey (easy to get as we have bees), dried fruits . I try to eat food in its natural way, the less processed the better. So it became already my habit for a reason. I found some good stuff about how the body uses sugar from the book Abundant health.

Sugar is very important element in nutrition, but its nature and use are little understood by most people. The easy way to understand the matter is to begin with sugar as it is found in normal, healthy blood, where, for every thousand parts of blood, one part must be sugar, - the substance the body cells burn to produce heat and energy for use by all parts of the body. This blood sugar is derived from certain kinds of food. The body can convert a portion of the protein and fat intake into this sugar (glucose), but the larger part of the body's supply is secured from starch and sugar.

Storage of sugarWhen taken in three meals to provide for 24 hours need, the supply is not uniform or steady enough; there is apt to be either a "feast" or a "famine". Too large amount would accumulate in the blood at one time unless there were some way to regulate it. For this reason temporary storage is provided in the skin, muscles and liver. The liver stores sugar in a "compressed" form called "glycogen", and on demand from the blood it releases it again as glucose for use as needed. When it is stored in the skin no chemical change takes place in it as simply an outflow from the blood stream and an inflow back into it which is called storage by "inundation". The storage of glucose in the cells is called storage by "segregation" which is more complicated than storage by "inundation". Shortage in the cells and release from them is thought to be under the control of the nervous system in cooperation with glands on internal secretion.
